Part A: Jerry and Michelle have 3 normal male offspring, 5
normal female offspring, and 2 diseased male offspring. Using the
most likely mode of inheritance based on this information, what are
the chances the first 3 offspring are diseased, and the
4^th is heterozygous for the mutant allele? Note that
neither Jerry nor Michelle display the diseased phenotype.

Part B: What are the chances the first offspring is diseased,
the 2^nd is a carrier, and the 3^rd is
phenotypically normal?
